This book is ok...I think that since the time it was released, there are probably better animal books. I do like that it uses illustrations rather than photos. You can see amazing animal photography everywhere, so the illustration make it more unique. On page 64, there is a drawing of gorillas, and on top of the gorillas, there is a comically small bird (looks like a cormorant, or something)...it has to be a mistake. The scale between the gorillas and the bird is waaaaaaay off. No matter...I purchased the book used, and my 4-year-old enjoys it very much.
